Abstract Carbon films with two different kinds of sp 2 nanocrystallited structure were investigated to study the stick-slip friction in-situ and ex-situ tests. In-situ transmission electron microscope (TEM) observation nanofriction tests revealed that origins stick slip varied shear stress film deformation. At stage, gradually increased contact strengthened until reached strength break interfac...

Abstract We study the influence of rubber transfer films on sliding friction between rectangular blocks and a concrete surface. present experimental results for coefficient compound surface contaminated by another compound, two different pairs (A, B) (C, D) compounds. For same compounds, we theory which illustrate relative importance viscoelastic adhesive contribution to friction. correlate cal...

Introduction In wood industry, adhesive bonding is one of the key process steps. To ensure continuing technological progress in wood industry it is necessary to explore new possibilities of improvement in adhesive bonding. The potential routes for performance improvements suggested by a state of the art report issued by COST Action E13 Wood Adhesion and Glued Products (Dunky et al. 2002) focus ...

Insect adhesion is mediated by thin fluid films secreted into the contact zone. As the amount of fluid affects adhesive forces, a control of secretion appears probable. Here, we quantify for the first time the rate of fluid secretion in adhesive pads of cockroaches and stick insects. The volume of footprints deposited during consecutive press-downs decreased exponentially and approached a non-z...

The role of microtubules in the spreading of cells from the liver-derived IAR2 rat cell line was studied. Cells in the control medium seeded on a flat isotropic glass surface rapidly spread to form discoid shapes. Spreading in colcemid-containing medium was disorganized and delayed; partial reversal of spreading was observed. Nevertheless, even in the presence of colcemid the cells finally spre...

Uniform Fiber Bragg Grating sensors based on Polarization-Maintaining fibers are designed for simultaneous longitudinal strain and temperature measurement of Carbon Reinforced Polymer laminates. Panda, Bow tie Pseudo-rectangle optical fiber shape sections investigated employing three different embedding methods, each fiber. The simulation accurately takes into account that the embedded in unidi...

Aluminum aminoterephthalate MOF particulate materials (NH(2)-MIL-101(Al) and NH(2)-MIL-53(Al)), studied here as components of self-detoxifying surfaces, retained their reactivity following their covalent attachment to protective surfaces utilizing a newly developed strategy in which the MOF particles were deposited on a reactive adhesive composed of polyisobutylene/toluene diisocyanate (PIB/TDI...

This paper briefs the photothermal reliability studies we conducted on different encapsulation materials for some U.S. PV companies that are subcontractors of the Photovoltaic Manufacturing Technology (PVMaT) program. The results indicate that the photothermal stability of two foreign ethylene vinyl acetate (EVA) films is dependent on the formulation, curing method and condition, as well as acc...

A new protocol for fabrication of glass microchips is addressed in this research paper. Initially, the method involves the use of an uncured SU-8 intermediate to seal two glass slides irreversibly as in conventional adhesive bonding-based approaches. Subsequently, an additional step removes the adhesive layer from the channels. This step relies on a selective development to remove the SU-8 only...

Abstract Amorphous carbon films have attracted substantial interest due to their exceptional mechanical and tribological properties. Previous studies revealed that the amorphous exhibited lower coefficient of friction (COF) because transformation in bond structure from sp 3 -C 2 during processes. However, mechanism for such a is not well understood. This study conducted get an insight into meta...
